Closing form while processing
Hi
I have a while loop in a win form code. Also a close button on the form
calls Me.Close. How can I let the user close the form using the close button
even though the loop is still running? Right now pressing Close button waits
for loop to finish and then closes the form.
Thanks
Regards

Getting record count
Hi
I need to go through a resultset record by record. Currently I am using an
OleDbDataReader to achieve this. Is there a way to get the total record
count so I can notify users of the progress? If not via OleDbDataReader, is
there another way?
Thanks

Reflection: Distinguishing property from WithEvents field
Using reflection I need to find all (private and public) fields, defined with

Extended File Information
Can someone please direct me to information on how, using VB.Net 2008 under
Windows XP, can I programmatically retrieve extended file information, like
Title, Subject, Author, etc. from a Windows Media file (*.wmv)? You can see

Summary tab.

Zoom applet
Years ago, there used to be an applet called (perhaps) Zoom or ZoomIn that
shipped with the SDKs. The applet acted as a magnifier that could be drug
around the screen and it would magnify whatever is was over. This was
especially useful for seeing the exact pixel representation of controls.
Does anyone know if this is still around for download and what is it called?
Also whether is w...

Help With ICloneable And Deep Copy
Hi all. I'm trying to implement ICloneable with the intent of making

System.IO.Pipes.NamedPipeClientStream.Connect
When a client thread calls Connect, it blocks until the connection is made.
If the server is busy, the client will block until the server is no longer
busy (ie until the server calls WaitForConnection). If the server is not
running (ie the pipe does not exist), the client side still blocks. I have
tested this - run the client, observe that it blocks, run the server, the
client unblock...

Help with PDF
Hi All
Could some kind soul help me with advice on PDF generation. Our company
seems to have gone PDF mad and I am expected to produce outgoing reports in
..pdf rather than .txt, .xls or .csv (as they are now).
No worries with buying a component to fit in with VB.Net (2008). I would be
grateful for any advice on the best (and easiest to understand :)) component
for the job.
